background: researchers have suggested that the general self efficacy can substantially contribute to organizational theory research and practice. Therefore it is important to study the psychometric properties of schwarzer and jerusalems general self efficacy scaleamong staff of the state universities in Tehran. Method: 400 employees who completedthe GSE scale were selected using multistage cluster sampling method. Results: the results of principle components analysis obviously supported the one factor structure of GSE. Conclusion: considering the results as well as the authentic history of research on the GSE scale at a global level it can be concluded that the GSE is an appropriate instrument to measure self efficacy of university staff that can be used in other researches.

Background: in recent years the number of researches in the field of positive psychology has increased. Therefore studying psychometric properties of the most widely used tools in this field like happiness is of a great importance. Objective: the present study aimed at exploring the psychometric properties of Persian version of the oxford happiness questionnaire among college students. Results: the results of the confirmative factor analysis indicated that the factorial structure of the questionnaire was one dimensional. Moreover the coefficient of convergence and divergence validity for questionnaire was high and acceptable.

The Big Five Inventory (BFI-10) is a shorter, 10 item version of the BFI. It was designed to be used when time limitations in a research protocol does not allow using the longer BFI. It measures personality in one minute or less. In this report, we evaluate 10-item measures of the Big-Five personality dimensions. The current study was conducted in survey and cross sectional as well as ex-post facto research context. A group of 317 randomly selected normal participants took part in this research. Principal component analysis extracted five factors which were labeled big five traits. However, for this scale other type of validity (convergent validity) and three reliabilities (test, retest, split half and internal constancy) were reported. The factor analysis and validity reliability coefficients demonstrated the same factor structure that previously found. Based on these results, it was concluded that BFI-10 contain good validity and reliability in Iranian population and it can be used, as valid measure in personality screening studies.
